I read that only 2015s and newer officially have the lizard batteries, but 2014s and even some 2013s might have the lizard batteries.Is there any way to check if a specific 2014 is one of the ones with the better battery?

Perhaps what you read is that Nissan changed battery chemistry starting with cars built during 4/13 (part way into the '13 model year). This was a substantial improvement for hot weather use over the previous chemistry. The chemistry was then changed again at the start of the '15 model year - the so called "lizard battery". And yes. battery replacements done in the past two years plus have received the lizard chemistry.
